Shriek of the Mutilated (1974): Cast & Plot

On Boot Island, Professor Ernst Prell, Alan Brock a seasoned Yeti investigator, leads four graduate students—Keith Henshaw, Karen Hunter, Tom Nash, and Lynn Kelly—into the remote mountains. The night before the expedition, Prell invites Keith to dinner, where they sample an exotic dish known as gin sung, a flavor as strange as the journey ahead. The off-campus party that follows brings a chilling rumor: Spencer Ste. Claire, a former student played by Tom Grail, tells everyone the story of Prell’s last expedition, a tale in which only the professor and the former pupil survived. The mood shifts quickly from campfire bravado to brutal reality as Spencer’s own night ends in tragedy—he slits his wife’s throat, and in a cascading reversal, his wife drowns him with a toaster in the bathtub.
